我已经下载了：--
libwebsockets-1.0-chrome25-firefox17
从;--
http://git.warmcat.com/cgi-bin/cgit/libwebsockets/
我必须安装 websocket 库。但它不包含配置文件。根据安装说明：-
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
它还包含文件：---
configure.ac
autogen.sh
请建议在 linux 中生成配置文件的命令？
